What's the cause of cancellations in our spectra?
¶
Spectra evolving with dephasing
¶
Difference of absolute values of individual spectra
¶
Look at cosine of phase difference
¶
$$ I\propto \omega^2\lvert j_{inter} + j_{intra}\rvert = \omega^2\left[\lvert j_{inter}\rvert^2 + \lvert j_{inter}\rvert^2 + 2|j_{inter}||j_{intra}|\cos(\phi_{inter} - \phi_{intra})\right] $$
Look at phases
